Abstract: Disclosed is a heat sink with a set of fins that can be positioned in a plurality of orientations relative to a heat-generating electronic component to which the heat sink is thermally coupled. The heat sink has a base engaged with a rotary member with the fins. A drive member is coupled to the rotary member to rotate the rotary member relative to the base in response to a control signal. The drive member may engage the rotary member via a gear. The heat sink may have a temperature sensor coupled to the base and a controller. The controller may generate the control signal to the minimise the temperature of the base by aligning the fins with the airflow. The drive member may be an electric motor.
